sleep command in compiler no warning

[doppler]

Getting the math right was always my biggest pet peeve.  Like using an unsigned byte by accident on a signed word location of memory.  Lot's of high level and even assembler languages let you do dumb things.  Not stopping or warning, just sit back and laugh at you.  Yes doing all the math directly does speed up the program.  But like going mach 2 doesn't work all the time.  Eventually your going to hit something without using navigation.
